MASSAGING MACHINE I Filed Aug. 26, 1929 INVENTOR Patented Mar. '3; 1931 JOHN T. WELCH, OF DOWAGIAC, MICHIGAN MASSAGING MACHINE App i n m August 6.19%. ruia1 1az38$76 The main objects of this invention are: First, to provide a massaging or exercising machine which is very simple and compact in structure and at the same time power- 125 ful and durable. 1

Second, to provide a structure having these advantages which runs quietly and with aminimum of vibration.

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the v1 accompanying drawing in which:

Fig. 1 is a side elevation of my improved massaging machine, the strap-like applicator being partially broken away and the machine being shown in' anchored relation to a 2 wall.

Fig. 2 is a fragmentary plan view, a portion of the housing or gear box being removed.

Fig. 3 is a view mainly in transverse section on line 3-3 of Figs. 2 and 4.

Fig. 4 is a fragmentary View mainly in longitudinal section on line 44 of Fig. 3. In the embodiment illustrated the supporting standard 1 is formed of a piece of pipe or tubing provided with a floor plate 2 at its lower end and a top plate 3. .These plates have sockets to receive the ends of the tubing. The base plate 4 is provided with supporting engaging lugs 5 adapted to enter .35 holes in the plate 3, and with spaced ears 6 adapted to rewive the eye 7 of the screw 8 between them. The screw is threaded into the wall indicated at 9 and connected to th cars by the pin 10. I

The motor. 11 is mounted on the base 4. The base 4 is also provided with a gear box base 12 having bearings 13 and 14 for the driven shaft 15. 1 The driving shaft 16 of the.

motor is supported in a bearing 17 on the motor housing. This driving shaft is provided with a driving pinion 18 meshing with the gear 19 on the shaft 15.

The gear 19 is preferably of fiber, raw-hide or other suitable material to eliminate noise .50 in the gears. This gear is secured to the gear box 12 by means of screws as 29. The actuated .member is provided with a series her is practical to use motors of small horse drum20bymeau 0f crewsill an i s ur to th ahaft by means 10f the se c ew Thi arrangement permit the gearand drum to he .assemhledhs a u it, 1.1:.opp.e1 .lin s the gear box and the shaft inserted.
